Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Backfiring through the intake is in most cases caused by a timing concern and its likely you have your distributor installed incorrectly or the firing order is off. Start first with rechecking your distributor to be sure the rotor point to #1 on the cap with the #1 cylinder at top dead center on the compression stroke. If the distributor aligns right then recheck your firing order.

I have double checked the firing order and made sure that the rotor button is point towards no. 1 on tdc. I am at a total loss here
Customer: replied 7 months ago.
Does it matter what direction the body of the distributor sits as long as the rotor is on no. 1
Expert:  Ron replied 7 months ago.
It should not matter as long as the rotation and firing order are correct. Are you sure you got the cam timing right?

I want to thank you for you time and response. it turned out to be trapped air in the fuel system from being open so long I guess, but I cracked open the fuel lines got a bunch of air with a small amount of fuel retightened the lines and she fired rite up.
